To all whom it may concern Be it known that I. Graver: lViLLiAMs. a citizen of the United States, residing at Empire, in the county of l islker and State.

of Alabama, have invented certain new and useful Improvements in Signals for Rail: roadilrossings; and i do hereby declare the following to be a. full.- clear, and exact de-' scription of the invention, such as will onsble others skilled in the art to which it appertains to make and use the some.

The invention relates to improvements in signals for railroad crossings.

Theobject of the present invention is to irz'iprove the construction of signals for milroad crossings and to provide a simple, practical and efficient railroad crossing signal equippedwith a si nel adopted to be operated by A train at o distance from a crossing and capable, after the train has mitometiczilly dropping out of passed, oi?

that the railroad track sight for indicating may be crossed with safety.

With these and other objects in. view the invention consists in the construction and combination and arrangement of hereinafter fully described, illustrated eccointgaiiying drawings and pointed claims hereto appended. it being out in the midersrood that various changes in the form,

ion and minor details of construcbe resorted to Without departing i \J the 1. tion ins from the spiritor sacrificing any of vsntcgcs of t e invention.

in the drawings Figure 1 is a'plan view oi? a safety railroad crossing signal constructed in accord ance with this invention,

Fig. 2 is a side elevation of the some Fig. 8 is a. detail sectional view on F-ne 3-3 of Fig. 2,

Fig. is a detail perspective view of the deoressibie train actuated device.

Fig. 5 is a. detail view of the deprcssible train actuated device illustrating a. modification of the invention.

Lilac numerals of reference designate corresponding parts in all the figures of the drawings.

The approach of strain is indicated at e. crossing-g by a danger flag 7 located at one side of the crossing and. secured to an arm of a. recs; shaft-9 consisting; of e series of coupled together by sleeves i0 and jonrnsied in suitable bearings 1.1 015 stands 12. The stands 12 which are provided at the the bottom with base or attaching flanges 13 are secured to the upper faces of the cross ties and may be arranged at any desired. intervals. The rock shaft is provided at its outer ends with an operating arm or crank com.- posed of spaced sides M and 15 and a connection portion lfi'ztnd adapted. to be swung 'l ..,.1 1 i a 1-.-

oovmwsr dry o depiessible device 1t. flhe side 14: ofthe crank or operating; arm is secured to the adjacentend of the rock shaft and the other side 15 is provided at its inner end with. s pi ot 18 mounted in a bearing 19 of stand or bracket 20. The depressible device 17 is adapted to be actuated by the Wheels of 21 passing train consists of a plate or body portion of substantially segnle tcl form normally projecting above the trend of the adjacent rail and presenting an upper rounded or convex face 21 to the Wheels of a train. The de pressible train actuated device provided with depending substantially L-shsped arms 22 extending to and connected with the transverse connecting portion 16 of the crank of the r ck shaft.

In practice the parts will be of proper proportion to secure the desired jthrow oi the carrying arm "which is provided with 2. Weight preferably in the shape of a bell for returning the flag carrying arm its lowered position rafter 2,. train has passed. Also any other suitable signaling device may be applied to the arm 8. Also in practice the flag and 01 crating mocha nism will be located at each side of the cross ing for indicating: the approach of a. train from either direction. Ordineriiy the operto the whistle board so that am ne time will be afforded for persons at the crossing to get out of the way of an approaching train. The depressibie train actuated device may be construc'ted'in any suitable manner so as to present a. substa htielly rounded or convexed face to the Wheels of a. train and spaced arms or portions for connection with the crank of the rock shaft.

The flag may be of any desired design and may bear any inscription and it may consist of the ordinary red danger signal "flag employed on railroads.

In 5 of the drawing is illustrated a modification of the depressible train operated device. This device consists of ecurved resilient bar or spring 2% provided ctw its ends with eyes and her ing spaced i eedoee crank arm of the rock' shaft. The eyes atv the ends of the curved bar or spring 24 en- .able the same to be mounted in any desired manner.

What is claimed is v 1. A safety railroad crossing signal including a longitudinal rock shaft provided adjacent to the crossing with an arm, a danger signal carried by the arm, a crank member connected with the rock shaft, and adepressibl train operated device consisting of a body having a rounded upper face and an arm extending from the body and connected with the said crank member.

2. A safety railroad crossing signal including a rock shaft designed to be mounted at one side of a: trackand provided adjacent to the crossing with an' arm and having a Weight and provided With a signal flag, a. crank connected with the rock shaft and composed of spaced sides and a connectingportion, and a depressibie train actuated device located adjacent to the track and having an arm connected With the said crank.

3.'A safety railroad crossing signal ineluding a-rock shaft designed to be arranged at one side of a track and provided adjacent to the crossing with .an arm, a signal carried by the arm and extending from the rock shaft in one direction, a crank extending from the rock shaft in the opposite direction and composed of spaced sides and a connecting portion, and a depressible train actuated"device consisting of an approxi mately segmental body portion and spaced IL-shaped arms entending from the body portion to the connecting portion of the crank In testimony whereof I afliX my signature in presence of two witnesses.
